any advice on how to relate a current affairs issue e.g. Trump's tariffs to a firm and its clients for an upcoming AC?
I'm gonna give up my "strategy" here... partially as I'm not sure I'll even make it to an AC, and it'll potentially go to waste.
The obvious answer to me is for clients that operate internationally being directly impacted. Then there is uncertainty around investment/marketing/deal decisions and risks because of this. Beyond that, the impact it can have on the US/EU economy in certain markets, the UK services "export" economy, currency conversions/values, and other countries' competitive advantages from US costs going up (for firms operating in other countries). Then there will be inflation and price level, unemployment, etc., in terms of impactful macroeconomic decisions. There are probably 7 or 8 knock-on impacts from that. Then also Trump's specific demands, what he wants and the risks of certain countries *cough* UK *cough* giving into demands
As somebody who follows other headlines, tariffs are just one of maybe 10 pieces of the macroeconomic puzzle (including Venezuela, Iran, Powell, etc.). As for specific client industries, look at the clients/sectors the firm represents, and figure out who will be impacted, and by which means.
